The radar watched 63 sources across 32 tools this window and published 29 changes; these are the thirteen worth your attention, ranked. That's three more than the typical ten: five of them (Kimi's Moonshot V1 sunset, its new Anthropic API format support, Mistral's OCR 4.1 GA, and two Pinecone pricing changes) were detected right at last week's window boundary and only got reviewed now, on top of a genuinely dense week for pricing and deprecation news on its own — Claude Code's new default Fable model, a Copilot model cull, and Langfuse cutting session lifetime.

GitHub Copilot — Multiple GitHub Copilot models deprecated on October 2, 2026 GitHub Copilot will deprecate Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code, and Claude Opus 4.7 across every surface (Chat, inline edits, agent mode, completions) on October 2. Suggested replacements: Gemini 3.8 Flash for both Flash models, Kimi K3, and Claude Opus 5. If you pin a model in Copilot settings, check now, not on October 2.

Claude Code — Added Claude Fable 5.1 model with 1M context as new default Fable model Claude Fable 5.1 replaces Fable 5 as the default Fable model in Claude Code: 1M context window, $10/$50 per Mtok for input/output, and cache reads cut from $1 to $0.25 per Mtok. For workloads that lean on cached context, that's a 75% drop on the read side alone.

Braintrust — Monthly included credits reduced from $249 to $100 Braintrust cut the monthly included credits on its main plan from $249 to $100, a 60% reduction. Heavy evaluation users will burn through the included allowance faster and need to either buy more credits or scale back eval volume.

Langfuse — Security fix: JWT session max age reduced to 14 days Langfuse cut the default JWT session max age to 14 days, tagged as a breaking security fix. Sessions that used to stay alive longer now force a re-login after two weeks; automation that depends on long-lived sessions should budget for more frequent re-authentication.

Kimi API — Moonshot V1 model series discontinued with platform sunset Moonshot's V1 model series is off the Kimi API platform as of August 31; the pricing page no longer lists it at all. Anyone still pointed at a V1 model name needs to move to a current one now, without a grace period.

Pinecone — Bulk import credit of $250 (1 TB) no longer offered for new subscriptions Pinecone dropped the one-time $250 (1TB) bulk import credit for new Standard and Enterprise subscriptions; imports from object storage now bill at the standard $0.25/GB rate from the first byte. If you were budgeting a large first import around that credit, it's gone.

Kimi API — Kimi API now supports Anthropic API format in addition to OpenAI format The Kimi API now speaks the Anthropic API format alongside OpenAI's, so it can sit behind Claude Code and other Anthropic-SDK integrations without a translation shim in between.

Mistral — OCR 4.1 model released and now Generally Available Mistral's OCR 4.1 (mistral-ocr-4-1) is now generally available, ready for production OCR workloads rather than the preview tier.

Pinecone — Full-text search and Documents API reach general availability Pinecone's full-text search (BM25) and the new Documents API reach general availability on API version 2026-07: you can now combine full-text, dense-vector, and sparse-vector ranking in one schema-based index, plus bulk document operations.

Zep — Neo4j MCP server behavior change: NEO4J_DATABASE setting now honored for all operations If you self-host Zep's Neo4j MCP server with a custom NEO4J_DATABASE (anything other than the default 'neo4j'), earlier versions silently split your data: writes went to the configured database while reads and searches hit the server's home database. The fix makes every operation respect the configured database consistently, but check your home database for orphaned writes before assuming the upgrade alone fixes your data.

Vercel AI SDK — Cursor Cloud Agents now supported on Vercel Sandbox infrastructure Cursor's Cloud Agents can now run on Vercel Sandbox: scale-to-zero workers, isolated microVMs, and durable orchestration, all on infrastructure you control instead of Cursor's own hosting.

Pinecone — cohere-rerank-3.5 deprecation deadline moved from July 31 to August 31, 2026 Pinecone's cohere-rerank-3.5 auto-migration, originally set for July 31, actually landed a month later on August 31: requests are now silently served by cohere-rerank-4-fast if you never moved off it yourself. If your rerank results shifted in the past week, this is why.

Neon — Neon backend now available in AWS Europe (Frankfurt) Neon added an AWS Europe (Frankfurt, eu-central-1) region, alongside the existing US East (Ohio). European teams now have a local option for latency and data-residency requirements.
